Needs some serious review with iOS7

I used this app over 18 months ago with great success. Recently had to pay for it again at $8.99 I expected it to work wonderfully. I update my iOS and the entire 3 weeks of my weight loss data is gone, my start date and days to go are wrong and the measurements and weight cant be recorded as a keyboard doesnt come up to enter the numbers!!! I am highly disappointed and would rate this app 5 stars if I could use it properly. Its very disheartening to be 3 weeks into a diet for someone who uses it faithfully...please fix!
